Injury to the ulnar collateral ligament (UCL) of the thumb requires imaging for diagnosis of surgically important entities such as the Stener lesion. Historically, routine radiography including stress views does not allow such diagnosis and is potentially detrimental to patient care.

How do you test for Stener lesions?

Xray – of D1 (thumb) – assess for fracture, avulsion of Ulnar collateral ligament. US – of D1 (thumb) – assess for Stener Lesion. MRI – If US inconclusive or not matching clinical impressions, MRI can provide a more definitive visualization of the UCL, adductor aponeurosis and evidence of boney edema from injury.

Can physical examination create a Stener lesion?

Conclusions: Performing a physical examination to assess the amount of instability of an ulnar collateral ligament injury did not create a Stener lesion if the exam was performed in a controlled, gentle manner with the thumb held without rotation.

What is a Stener lesion?

A Stener lesion is a complete tear of the ulnar collateral ligament (UCL) from the thumb proximal phalanx at the level of the metacarpophalangeal (MCP) joint that is displaced superficial to the adductor pollicis aponeurosis, leading to interposition of the aponeurosis between the UCL and the MCP joint.

What causes a Stener lesion?

A Stener lesion occurs when the thumb is forcefully abducted and the distal attachment of the ulnar collateral ligament (UCL) at the metacarpophalangeal (MCP) joint is traumatically avulsed from its insertion into the base of the proximal phalanx of the thumb.

The metacarpophalangeal joint or MP joint, also known as the first knuckle, is the large joint in the hand where the finger bones meet the hand bones. The MCP joint acts as a hinge joint and is vital during gripping and pinching. When arthritis affects the MP joint, the condition is called MP joint arthritis.

Can gamekeeper's thumb be treated nonoperatively?

Nonoperative treatment can be considered for partial tears (grade I or grade II) of the UCL, which usually involve an isolated rupture of the proper collateral portion of the ligament. This may be treated with immobilization in a thumb spica-type cast for 4 weeks.

How did gamekeeper's thumb get its name?

Gamekeeper’s thumb is an insufficiency of the ulnar collateral ligament (UCL) of the metacarpophalangeal (MCP) joint of the thumb.

Do all UCL tears require surgery?

Does a UCL injury need Tommy John surgery? If enough of the UCL is torn that an athlete continues to have symptoms with throwing, surgery is often still necessary. Some athletes with partial tears might be able to return to sports with rest for up to six weeks and physical therapy.

Do you need surgery for a UCL tear?
